Parameters:
  • Working voltage range: DC 8~30V
  • Temperature measuring range: -40~120°c
  • Temperature error correction setting range: -5 ~ 5°c.
  • Voltage measuring range: 8~28V
  • Voltage error correction setting range: -0.5V~0.5V
Note:
  • 1. It should be powered by DC 8~30V(pure DC power supply), it will light on if connect with power supply; it is equipped with battery(battery module CR927) in the back, which is used to record time, it will support time on the meter keeping going even if power off.
  • 2. It is not recommended to apply to 24V battery or truck, for that the voltage will be about 30V when the generator charging, which may destroy the meter.
  • 3. There are two waterproof probe(one of length is 1.5 meters, the other is 0.3 meters), can be used to measure the inside and outside temperature of the car.
  • 4. The temperature probe is very sensitive, if needs to compare the result with other thermometer, it would be better to bound the probe with the thermometer, otherwise the results would be much different even their location are very close in the same car, which is proved by experiment.
Using Instruction:
  • A). Time, date, temperature error correction, voltage error correction, brightness adjustment.
  • Under normal using state(no flashing state)
    • 1). Press the "left" key, "minute" will begin to flash, then pressing the "right" key to increase "minute" value, you can set the "minute" value in the range 59~0.
    • 2). Press the "left" key, "hour" will begin to flash, then pressing the "right" key to increase "hour" value, you can set the "hour" value in the range 23~0.
    • 3). Press the "right" key, it will switch to date adjustment, the ":" indicator light will be off, and "day" will begin to flash, pressing "right" key to increase "day" value, you can set "day" in the range 1~31. Then press "left" key, "month" will begin to flash, pressing "right" key to increase the "month" value, you can set the "month" value in the range 1~12.
    • 4). Press "left" key, "year" will begin to flash, pressing "right" key to increase "year" value, you can set the "year" value in the range 2012~2050.
    • 5). Press "left" key, it will enter the RT0 channel temperature correction, LED displays "Ac:xx", xx is the temperature correction value, unit is degree. Pressing "right" key to adjust the temperature error correction value in the range -5℃~5℃, positive number means increased, the negative means reduced. And then pressing the "right" key to enter the RT1 channel temperature correction, LED displays "AC:xx", adjustment method is the same as RT0.
    • 6). Finished the temperature error correction, press the "left" key, LED displays "U x.x", which means entering the voltage error correction, x.x is correction value, in the range U0.5~U-0.5, positive number means increased, negative number means reduced, unit is V, for example U-0.1, it means reducing 0.1V.
    • 7). Press the "left" key, LED displays "dd:x", it enters the definition function of cycle time display, you can press "right" key to adjust, (dd:1)time+RT0+RT1, (dd:2)time+RT0+voltage, (dd:3)time+voltage.
    • 8). After adjusting the DD option, then pressing the "left" key to enter the brightness adjustment, LED displays "LL:xx", the higher the value, the brighter the light. After setting the brightness, pressing the "right" key to save all data, and return to the normal display state.
  • B). Display mode switch.
    • In the non-adjusted state (no flashing state), pressing "right" key will switch display mode, you can wait for a few seconds to check whether it is in the display cycle, if it didn't switch, please try again to press the "right" key, it will switch display mode as sequence ① shows time only→ ② shows the date only → ③ shows RT0 temperature only → ④ shows RT1 temperature only → ⑤ shows the voltage only→ ⑥ time, RT0 temperature, RT1 temperature, voltage, they will alternately display, and save the last mode, even if power off and then boot.
  • C). "DF": set the time interval of alternate display cycle, please don't set it to "0", otherwise it will switch to black screen.
Package Including:
  • 1 x Car Clock Temperature Voltage Meter ( 3in1 Digital Meter/ Monitor/Tester )
